Hard diskdrive mobile rack cooling arrangement

ABSTRACT

A hard diskdrive mobile rack includes a rack adapted to hold a hard diskdrive, the rack having a plurality of air vents through a bottom panel thereof and a plurality of hook holes symmetrically provided at two sides of each air vent, and a plurality of induced-draft fans respectively installed in the air vents.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a mobile rack for hard diskdrive and, more specifically, to a hard diskdrive mobile rack cooling arrangement in which induced-draft fans are installed in respective air vents at the bottom side of the hard diskdrive mobile rack for dissipation of heat from the hard diskdrive upon its operation.

[0002] During the operation of a computer, heat must be quickly carried away, keeping the temperature inside the computer within the set working temperature range. Various effective CPU and AC adapter heat sink and fan cooling designs have been disclosed. However, few effective hard diskdrive cooling designs are commercially available. For cooling the hard diskdrive of a computer, it is generally to install a fan in the back or front panel of the casing of the computer in front or at the back side of the hard diskdrive. This arrangement is less effect, and does little help to the cooling of a mobile hard diskdrive.

SUMMARY OF THE INVENTION

[0003] The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a hard diskdrive mobile rack cooling arrangement, which quickly carries heat from the mobile hard diskdrive upon its operation. According to the present invention, air vents are provided at the bottom side of the hard diskdrive mobile rack, and induced-draft fans are respectively installed in the air vents and controlled to draw hot air out of the rack upon operation of the hard diskdrive in the rack.

BRIEF DESCRIPTION OF THE DRAWINGS

[0004]FIG. 1 is an exploded view of the present in invention.

[0005]FIG. 2 illustrates the relationship between a hard diskdrive mobile rack and a hard diskdrive according to the present invention.

[0006]FIG. 3 illustrates an alternate form of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0007] Referring to FIG. 1, a hard diskdrive mobile rack in accordance with the present invention comprises a rack 1, at least one, for example, two induced-draft fans 2, and a hard diskdrive 3. The rack 1 comprises a bottom panel 11, two air vents 12 through the bottom panel 11, and a plurality of hook holes 13 symmetrically provided at two sides of each air vent 12. The induced-draft fans 2 each comprise a plurality of hooks 21 respectively hooked in the hook holes 13 of the rack 1, and a fan blade and motor assembly 22 suspended in one air vent 12. The hard diskdrive 3 is mounted in the rack 1 and covered over the air vents 12, and fixedly fastened to the bottom panel 11 by screws 23.

[0008] The width of the induced-draft fans 2 is shorter than the rack 1. Therefore, there is sufficient space provided at two sides of the induced-draft fans 2 for exhaust of heat source efficiently.

[0009]FIG. 3 shows an alternate form of the present invention. According to this alternate form, each induced-draft fan comprises a frame 14 formed integral with the bottom panel 11 of the rack 1 and bridged over the corresponding air vent 12, and a fan blade and motor assembly 22 detachably mounted on the frame 14.

[0010] It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed. 

What the invention claimed is:
 1. A hard diskdrive mobile rack comprising a rack adapted to hold a hard diskdrive, said rack having a plurality of air vents through a bottom panel thereof and a plurality of hook holes symmetrically provided at two sides of each air vent, and a plurality of induced-draft fans respectively installed in said air vents, said induced-draft fans each comprising a plurality of hooks respectively hooked in the hook holes of said rack.
 2. A hard diskdrive mobile rack comprising a rack adapted to hold a hard diskdrive, said rack having a plurality of air vents through a bottom panel thereof, and a plurality of induced-draft fans respectively disposed in said air vents, said induced-draft fans each comprising a frame integral with the bottom panel of said rack and suspended in one air vent of said rack and a fan blade and motor assembly mounted in said frame.
